Indications and results of shunt operations in the treatment of patients with recurrent variceal hemorrhage.
None of the portasystemic shunts are ideal for all patients with recurrent variceal hemorrhage. Hemodynamic and clinical status should determine the type of shunt selected. Patients with a compatible anatomy, hepatopetal protal flow and controlled ascites are best served by a distal splenorenal shunt. Patients with variceal hemorrhage and medically resistant ascites are candidates for a side-to-side shunt, with consideration being given to an operation that avoids dissection of the porta hepatis. The end-to-side portacaval shunt should be used only in the emergency situation when other options are not available. However, due to the effectiveness of other therapies, such as sclerotherapy, in controlling bleeding, emergency shunts are rarely required. On the basis of the controlled trials of distal splenorenal shunt versus sclerotherapy, the latter is the initial treatment of choice with distal splenorenal shunt used promptly when sclerotherapy fails. Patients who live in remote areas, and noncompliant individuals may be best served with a distal splenorenal shunt as initial therapy.
